IMPROVEMENT IN STILLS.

The Schedule referred to in these Letters Patent and making part of the same.

To all Vwhom 1 t may concern:

Be it known that'I,JAMEs CAMPBELL, of Dayton, in the cou'nty ofl Rockingham and State of Virginia, have invented certain' new and useful Improvements in Stills; and I do liereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying on making part of this specification, in which is represented a vertical sectional view ofthe still.

Thelobjectof my invention is to construct a still that in one vessel shall be combined the singler and doubler, so that the advantages and results of both tinuous process instead of two, as heretofore practiced,

vessels, or else the drawing olf the liquorrso as to re- Iu my invention the still in which the singling, consisting of the fruit, grain, or mash,'is placed may be an independent vessel, or formed so as to he seated dion, as it were, like a cap.

This opening is surrounded by a vertical tube. Over this tube is secured, by a spring or other suitable retaining device, a cylinder, having a closed ortight top, but open at the bottom, and with a series of latl eral perforations around its lower rim or base. 5 The relativeydimeusions of the tube and cylinder are such that, when the'oneis secured over the other,

it shall so lit as to leave an annular steam-passage or the inner wall ofthe same, while sufficient space shall be left between the top of the cylinder andupper face of the tube, to insure the propendetlection, without danger of accident, of the steam, down through the passage or chamber, from which it escapesthrough the perforations into the outer or doubling-chamber.

To enable others skilled in the art to make and use myinvention, I will now proceed to describe its construction and operation. l

A is the still, which is of the ordinary form, andA constructed in the usual manner, and may be made of any suitable material. `This vstill A is provided with the ordinary openings c and a', for therinsertio'n constructed as to allow of its being used las an independent vessel, or, if preferred, as a cap for the steamboiler, in which case it is securely bolted or otherwise secured thereon.

In the bottom or base-plate of the still, and at the center thereof', is an opening, A. This opening A is surrounded by a vertical tube, B.- The top otl this tube B is open and entirely unobstructed, so as to allowof the free exit or escape of the steam. Over this tube B is secured `a cylinder, O. This cylinder C is closed at the top and open at the bottom, and is provided with a series of lateral openings c c.

The relative dimensions of the cylinder C and tube B are such that, when one is secured over the other, as shown in the drawing, a vertical annular passage or chamber b shall be left, the cylinder forming the it insures the cylinder being seated overthe tube in such manner as to leave the distancebetween the cylinder and tube uniform throughout.

The height ofthe cylinder is greater than that of the tube, which leaves a space, B', in which the steam, as

it is driven through the tube enters, and from which it is deflected down linto the passage b.

D is a 'spring or other suitable retaining-plate-foi the cylinder, and has its bearings against the inner surface ofthe arched or curved .breast of the-still A.

' E is a copper or other cap, and is iirmly secured in the neck or center-flanged opening of the still.

E is a goose-neck or vapor-duct, by which the vapor, as fast as it is,generated, is conveyed to the .condensing-room or other -like receptacle.

It will be observed that by this arrangement of parts two distinct and independent chambers are secured in a single still or vessel, one being the chamber l), and the otherF, which is between, and is formed hy the outer wall of the cylinder C and the inner wall of the still-A. The former is the singlei,` and the lattcr the doubler.

'Another' great advantagev oi' this forjn of still is, that is does not yrequire an independent boiler or condenser, provided steam-power is convenient, and it matters not for what purpose it may be designed, this still can be supplied from it, the spring D, under all circumstances, securely retaining the cylinder C in position; and, owing -to the fact that the cylinder C is not permanently attached, butso secured by the spring D as to be removed at pleasure, it not only enablesrthe still to -be used as either a single or double-chambered vessel, but affords ev'ery facility for cleaning the still` Y.

and the freeing the. chamber b of sediment and other impurities which will necessarily accumulate therein.

The operation is'as follows:

The fruit or mash, through the Aopening a, is introduced into thel still. The still is then, by a suitable pipe, connected with the boiler o r steam-generator, or

the still is secured directly tothe generator, being sen l curely seated and bolted thereon.

The steam passes up through the tube B into the chamber B, from which Ait is deflected down through the passage b, passing out at the openings c c, and-thence up through the fruit orv mash, which has thus been twice subjected tothe action of' the steam, once direct'and the other by Vthe steam passing through the chamber b.

.As my improvement is confined entirely to the still, I have I iinited [nyf description to the same, and would only remark that, in connection with the singling and
